Breadfruit \Bread"fruit`\, n. (Bot.)
   1. The fruit of a tree ({Artocarpus incisa}) found in the
      islands of the Pacific, esp. the South Sea islands. It is
      of a roundish form, from four to six or seven inches in
      diameter, and, when baked, somewhat resembles bread, and
      is eaten as food, whence the name.

   2. (Bot.) The tree itself, which is one of considerable size,
      with large, lobed leaves. Cloth is made from the bark, and
      the timber is used for many purposes. Called also
      {breadfruit tree} and {bread tree}.
